Caviar has been added to the list of protected imports. All species of sturgeon, the fish that produces caviar, will require a licence for import and export, said Agriculture and Fisheries Department endangered species officer Chan Yiu-king. However, less than 250 grams of caviar for non-trade or non-business purposes will not be covered. Before the amendment, only four types of caviar were controlled, two from highly endangered fish, said Mr Chan. 'We are adding 25 more species to the list, so every species is now under control,' he said. Several commonly traded pet birds have also been added to a list of endangered species and will need import and export licences. They include the hill myna, red-billed leiothrix, green avadavat and Java sparrow.
